Abstract:
Objective To investigate the characteristics and development of stops consonant production in Mandarin-speaking prelingually deaf children after cochlear implantation.Methods Thirty prelingually deaf children with a mean age of 4.37 years(SD=1.57)who received unilateral cochlear implantation(CI)under the age of 3,and thirty age-matched normal hearing(NH)children with a mean age of 4.02 years(SD=0.67)participated in the test.Word lists developed by Institute of Linguistics,Chinese Academy of Social Sciences were selected.The accu-racy of the stops(/b/,/d/,/p/,/t/,/k/,/g/)production performance and error types were analyzed.Results① The accuracy of children's stops output in the CI group was significantly lower than that in the NH group.The correct rate of each stop in the CI group was/b/＞/d/＞/p/＞/t/＞/g/＞/k/,and that in the NH group was/b/＞/p/＞/d/＞/t/＞/g/＞/k/.② The error type of CI children's stops output was similar to the NH group,with the main error being substitution error.The most common errors involved substitutions within the same place of ar-ticulation,and the more difficult sounds being replaced by the easier ones.③ With the increase in physiological age and hearing age,the total accuracy of stops production of CI children increased.The greatest progress was made 3 years after the operation,but the accuracy still did not reach 100％.There was no significantly correlation with im-plantation age(P＞0.05).Conclusion The accuracy of stops production in the CI group was lower than that in the NH group.With the increase of hearing and physiological age,stops production ability improved gradually and de-veloped rapidly within 3 years after the operation.
